Hot on the heels of learning that Jenny McCarthy and Jim Carrey have split comes news that two more Hollywood couples are calling it quits.Melissa Etheridge, 48, and Tammy Lynn Michaels, 35, have separated after nine years together. The singer and actress (respectively) were married in 2003 and have twins, son Miller and daughter Rose, who were born in October 2006 (Tammy was artificially inseminated with an anonymous donor's sperm).
Mel Gibson (pictured) and Oksana Grigorieva split after a year of dating. The couple also share a 5-month-old daughter, Lucia. The split is said to be very amicable and friendly, with no great blow-up leading to it — they simply decided to go their separate ways.
